Oscillators are widely used and have various applications in the generation of electrical signals at radio frequencies. The type of oscillator being discussed here is the SIT8008BC-21-18E-25.000000E oscillator. This article will discuss its application fields and working principles.

Application Fields

The SIT8008BC-21-18E-25.000000E oscillator is a type of miniature quartz crystal oscillator (MCXO). It is suitable for use in a variety of applications where a highly reliable and low power source of oscillation is required. This oscillator is primarily used in the telecommunications industry where it is used for timing and synchronization. It is also used in the radio frequency (RF) communications, medical instruments, and defence applications.

This oscillator is available in a variety of sizes, from the single-ended SMT package with 2.5 mm x 3.2 mm footprint, up to the larger through-hole packages with 9 mm x 11 mm footprint. The main advantage of this oscillator is that it offers a stable, low power, and low cost solution for many applications.

Working Principle

The SIT8008BC-21-18E-25.000000E oscillator is based on a quartz crystal resonator. This type of oscillator consists of a quartz crystal mounted between two piezoelectric plates. The quartz crystal is vibrationally tuned to a specific frequency determined by its size and shape. As the crystal vibrates, it generates a resonance frequency that is then amplified and output in the form of electrical signals.

The frequency of the oscillator can be precisely adjusted using the trimmer capacitor and by adjusting the voltage applied to the crystal. By increasing or decreasing the capacitance of the trimmer capacitor, the frequency can be changed smoothly over a range of several hundred kHz. In addition, the frequency may be tweaked even further by controlling the voltage applied to the crystal.

The oscillator is also equipped with a temperature compensator that helps to maintain and stabilize the output frequency over a wide temperature range. This compensator works by adjusting the capacitance of the trimmer to compensate for any changes in temperature.

Conclusion

The SIT8008BC-21-18E-25.000000E oscillator is a type of miniature quartz crystal oscillator that is suitable for use in a range of applications. It is especially useful for telecommunications, radio frequency communications, medical instruments, and defence applications. Its working principle relies on a quartz crystal mounted between two piezoelectric plates that vibrate at a certain frequency and generate electrical signals. This oscillator is also equipped with a temperature compensator that helps to monitor and stabilize the output frequency over a wide temperature range.
